Changes to ecosystems
Ecosystems are very sensitive to change. The living and non-living components of the ecosystem can be altered by either natural factors or human management.
Changes to the ecosystem caused by natural factors include:
Changes to the ecosystem caused by human management include:
- introducing more fish (fish stocking)
- altering the drainage of the land which may influence the amount of water
- changing the pH level of the water
- altering the nutrient levels of the water if fertilisers are leached into the water resulting in eutrophication
Any of these changes can have a negative impact on the ecosystem and could result in the collapse of a food chain.
